+## qwen_syn30v15_fixed (seed + five evolution steps, with software repositories)
+
+This is the corrected rerun of the `qwen_synthetic30v15` experiment above. The
+task-package defect that starved the earlier run of its nine web tasks is
+fixed, so **every variant here was evolved against the full 30 training
+trajectories** (bar six individual task failures noted below). It runs five
+evolution steps instead of one, with crossover enabled at cadence 2 and
+tournament parent selection, which produces a branching lineage rather than a
+linear chain.
+
+It is also the first entry in this dataset to publish the **evolved software
+repositories** alongside the trajectories. For each variant,
+`qwen_syn30v15_fixed_<variant>_software_repository.zip` contains the complete
+`shadow_interface/` source tree at that variant's git tag — the artifact the
+builder actually evolved, and the thing the agent imports at task time.
+`qwen_syn30v15_fixed/manifest.json` records each variant's git tag and commit,
+parent, operation, step, validation score, and file counts.

+
+**Only the validation columns are scores.** As above, the 30 synthetic training
+tasks have no verifiers and record a dummy constant zero labelled `UNGRADED:
+constant zero; use trajectories, not scores`. Validation figures come from the
+variant records in `shadow_evolution_osworld_v2_qwen_syn30v15_fixed.db`.
+
+The lineage branches: `seed -> if-001` and `seed -> if-002`, then
+`if-002 -> if-003` and `if-002 -> if-004`, then `if-003 -> if-005`. The peak is
+if-003 at 0.3390 mean partial, a 44% relative gain over the seed; if-002 has the
+highest full-credit count. The two steps after if-003 both regress, so this run
+gives no evidence that further steps would help.
+
+**Six trajectories are missing, and none of them is the old Chrome fault.**
+Across all 270 task runs there were zero `ECONNREFUSED` failures, zero browser
+UTC failures, and zero tracebacks. The gaps are: `s_003`, `046` and `072` in
+if-001; `072` in if-004; `007` and `072` in if-005. Five of the six are a
+transient outage of the `teamchat.site.hku.icu` task website, which recovered
+during the run; `007` in if-005 is a user-simulator failure. Task `072` is the
+seed's only full-credit validation task, and losing it in three separate
+variants depresses those variants' validation scores relative to the seed.
+
+The recorded run uses Qwen3.8-27B for both the builder and the task agent
+through OpenRouter/novita with fallbacks disabled, the Prime Agent harness, an
+interface-declared context window, 300 agent steps and a two-hour wall-clock
+limit per task, 40 concurrent VMs, and a deterministic scheduler with crossover
+cadence 2. Total API cost across the six variants was $396.13, of which $4.60
+was the builder and $391.53 the task agent.
+
+GitLab personal access tokens that a task agent minted inside a task VM's own
+GitLab instance have been redacted from the if-004 archive. Those VMs were
+destroyed at the end of the run; the redaction is a precaution, not a response
+to a live credential.
